ToJALL WHoM .rrr MAY ooNonRN:

Be it known tlmt, NATHAN'RIcHnnDsoN, of Gloucester, in the countyof Essex, :ind State of' lliassaeh'usetts, have invented certuin'new and useful Improvements in Ice-Crushers; and vI do herebydeclare that the following is o full and exact description thereof, reference-being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in combining wth'the crushing-wheels of :tn ice-crusher, :n number 4 ol" vibrating-teeth or spikes, which serve to split the larger pieces of ice, so thnt the teeth of thecrushermny grapple them. I v Y* I i Y '.loencblel others skilledfin the art to'make and use my invention, I' will proceed to set forth the description unduse. In the drztwingsl l I Figure 1 represents an elevation of the ice-crusher, a. pnrt of the hopper being broken out to show the internolparts'. l Y

Figure 2 represents in side elevation a. portion of the gear. Figure 3 is a, side elevation o f one of the cams, shownin front eleva-tion D D in iig. 1. 4 That portion of niy machine which .works as a crusher, including the toothed wheel I, and all belen' it, is

covered by' patent granted to ine,'Jun e 3,1862, und numbered 35,472, and as it is fully described in that patent, it is no1;I necessary to describe those parts now. I will therefore lcon'rine myself to the description of the new parts of the machine, namely, the splitting-spikes M M, &c and the pernting-d'eyice connected therewith.

M M M, fig. 1, are s eries ofpointed spikesor teeth, connected to a. solid heavy bar, H H, the eind of which i rests upon thecams D D. This bar, and consequently the teeth or spikes M M, are free to vibrate up and down, being guided bythe bar'K K, and being operated by the cams D D. The :shape of these cams is shown in fig. 3. AI? Pis a shaft, to whichthe cams D Drand pinion C are attached. `The cams D DIare operated by the pinion C, which meshes into the main wheel N.'

Having thus described my invention, I will now proceed to set forth my claim.

What I claini as iny invention, a'nd desire to secure by Letters Patent', is-

Innn ice-crushing mill, the vibrating-teeth or spikes M M M, 81e., operated bythe cams D/D, or their mechanical equivalents, in combination with the toothed crushing-wheels, substnnticlly es described and for the purpose setforth.,
